Can Ampère's circuital law be used to find electric field for a finite (say length l) current carrying this conductor at a finite point away from it?(adsbygoogle = window.adsbygoogle || []).push({});

If yes, then what will be Magnetic field due to a wire extending from (0,-a/2) to (0,a/2) carrying current “I” at a point (b,0) from it, if I consider a loop (circle here) of radius b/2 perpendicular to the x axis centered at origin?
